The Shasvastii Expeditionary Unit has been created to carry out military operations in enemy territory or politically sensitive areas. Their tasks include, but are not limited to, long term indirect activities, including guerrilla warfare and other low visibility and clandestine offensive operations. They are specialized in silent advance techniques, night combat and reconnaissance, and are as deadly as they are stealthy. The Aswuangs are instructed in the so-called Black Arts, meaning genetic malleability and regeneration abilities through organic material absorption. Which, in laymans terms, means they can devour living enemies to heal themselves or become more resistant. This ability allows them to operate in enemy rear echelons, feeding off enemy supply lines and field hospitals, turning them into fearsome adversaries. Amongst human line troops, news of this special units voracity spread quickly. The PanOceanian troops call them Aswuangs, a vampiric creature from Philippine folklore who eats human meat. The Aswuangs have become the new monsters of campfire horror tales. They are the nemesis of any troops assigned to night watch duty. Since their appearance on the battlefront, human armies have been forced to double the security of their rear encampments, tempting targets for these dangerous Shasvastii. The terrible reputation of the Expeditionary Unit makes their work easy, with human troops fleeing at the thought of being eaten. The Aswuangs are the awful man-eating soldiers of the Combined Army, embodying the true horror of the alien invasion
